this experiment is to derive Isopentyl acetate (banana oil) from the reaction of an alcohol and a carboxylic acid in a process called Fischer esterification (Fischer-Speier esterification). The name‚ banana oil‚ is due to banana odour released by formation of Isopentyl acetate. The alcohol and the carboxylic acid used in this experiment are Isopentyl alcohol and Glacial Acetic Acid. Both the overall reaction of Fischer esterification and the specific Fischer esterification reaction that was carried

Title: Esterification Objective: To recover and calculate the percentage yield of substance by esterification. Introduction: When a carboxylic acid reacts with an alcohol‚ the products are water and ester. The overall reaction is reversible and slow‚ as soon as the products begin to form‚ hydrolysis a reverse reaction of esterification occurs. To ensure the reaction is complete an acid catalyst is commonly used. The catalyst is usually concentrated sulphuric acid. This experiment covered 4

Ethyl acetate (systematically‚ ethyl ethanoate‚ commonly abbreviated EtOAc or EA) is the organic compound with the formula CH3COOCH2CH3. This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues‚ nail polish removers‚ and cigarettes (see list of additives in cigarettes). Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. The combined annual production in 1985 of Japan‚ North America‚ and Europe

alcohol‚ most commonly ethanol‚ or grain alcohol. An alcohol is a chemical compound whose molecular structure is comprised of a hydroxyl group –OH chemically bonded to a carbon. One of the simplest and most common esters is ethyl ethanoate‚ or ethyl acetate‚ a combination of ethanoic acid and ethanol. The ethyl ethanoate chemical reaction is C2H4O2 + CH3CH2OH C4H8O2 + H2O. As seen in this reaction‚ an acid and an alcohol are combining to form an ester‚ with a water molecule as a bi-product. The water

The purpose of this experiment is to synthesize isopentyl ester by an esterification reaction between a carboxylic acid and an ester. Carboxylic esters‚ like isopentyl acetate‚ are normally used to create artificial flavors. In the preparation of isopentyl acetate‚ esterification of acetic acid and isopentyl alcohol occurs. Esterification is an equilibrium shift to the product side using an excess of one of the starting components. In this experiment‚ the excess reagent is acetic acid because it

EXPERIMENT 5- A FISCHER ESTERIFICATION SYNTHESIS OF PEAR OIL One of the major uses of Esterification (C(=O)-C-R) is forming compounds with different odors which can be used to make different synthetic and natural flavorings. Using the chemical and physical properties of organic compounds‚ an ester was catalyzed from the reaction of a carboxylic acid with an alcohol‚ producing an odor similar to that of pear oil. The mechanism of this Fischer- Esterification process is outlined as follows:

Title: Esterification Objective: To synthesis acetylsalicylic acid by esterification. Introduction: A pleasant‚ often fruity‚ odor is characteristic of some of the simpler esters. Ethyl butyrate smells similar to pineapples‚ the odor of n-propyl acetate is reminiscent of pears and isopentyl acetate has a strong banana fragrance. Esters are derivatives of the carboxylic acids and contain the following functional group: The synthesis of an ester can be accomplished in one of several ways. An esterification

April 04‚ 2014 Fisher Esterification Introduction: Esters are one of the most common derivatives of carboxylic acids and are widely distributed in both nature and industry. A Fischer Esterification is the formation of an ester and water from alcohol and an acid. It is the simplest means of synthesizing an ester and requires the reaction of a carboxylic acid and an alcohol. The general reaction of Fischer esterification is‚ CH3CO2H + ROH ↔ CH3CO2R + H2O (reaction1) CH3COOH + ROH ↔

Investigation and Preparation of Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other.
